摘要:Nonlinear intensity response, namely gamma effect, of the projector-camera setup introduces phase error in phase-shifting profilometry. This paper presents a comparison of three phase error compensation methods: active, passive and adaptive, using a universal phase error model. The active method calibrates a gamma factor to modify the projected fringe patterns; the passive method implement an iterative procedure to work out an optimal phase map; the adaptive method compensate phase error based on Hilbert transform without any auxiliary conditions. Comparison Experiments were implemented in three and four phase-shifting steps, which demonstrated that the active method provided an excellent performance regardless the phase-shifting step, yet the passive method might fail when the phase error was large; the adaptive method could be in the same level as the passive method in four phase-shifting step.
